Bug 694382: Fix problems arising from recent pdf_obj changes.
Thanks to zeniko for spotting these problems.
When we close a document, purge the glyph cache to ensure that
no type3 glyphs hang around with pointers to pdf_obj's that
are now gone.
Pass doc to pdf_new_obj_from_str rather than NULL. We believe
that the reason this needed to be NULL is no longer valid.
Also, revert to using an int for ref counts.
In a quick test of our regression suite we only found 2 files
that ever made a refcount > 256 (and they never got larger than
768), but the potential is there for issues. Reverting to an
int until we can think of a better idea.
